What is claimed is:

1. A-machine for taking out a geological sample from a sample tube, comprising a. device to support the sample tube horizontally, a receiver arranged in continuance to the sample tube and a piston to push out the sample from the tube, the iston and receiver being moved or propel ed in the same direction with the same speed longitudinally along the in and out sides of the tube, substantially as shown and described,

2. A machine for taking out a geological sample from a sample tube, comprising a device to support the sample tube horizontally, a receiver arranged in continuance to the sample tube and a iston to push out the sample from the tu e,-the iston and receiver being moved or propel ed in the same direction with the same speed longitudinally along the in and out sides of the tube, in which the piston rod is provided with a rack geared with a pinion and the "receiver is of semi-circular form having legs for sliding upon a rail, the iston rod and receiver being interconnecte with a rod, substantially as shown and described.

In testimony whereof I afiix my signature.
